b2650 loader bucket too fast.

Best answer. You will get used to it.
Remember the joystick is not ON or OFF, you can control the speed with the amount of input.

You know it's a 2-stage dump control on the B2650, right? The first half of the loader lever dump is bypass mode ("fast dump"), then past the indent switches to valved mode, with full release speed control.
I hsve never used a Kubita loader with a four position bucket spool.
My LA525 is three positions with fast dump only and I can still meter dump speed with no problem.
On the four position valves can you still meter speed in the fourth position or is it just a slower "max" speed with more force?

okay, bring me up to speed here. I understand a two stage dump...got it on my mahindra. On the b2650 is the fast dump (as stated above) first?, followed by the controlled dump?
As to 4 position valves...are you talking about up/down/dump/load?

Four position valve means the spool has a neutral + 4 diffrent shifted positions. The bucket and boom spools on your loader are both 4 position. On my LA525 the bucket spool is 3 position and dump is always regenerstive.
Regenerative dump is not "unontrolled". It can be metered exactly like a non-regenerstive spool. Its not clear to me that the fourth non-regenerative dump position on a Kubota loader valve can be metered.
My understanding is Kubota valves put regen before normal action which, if you think about the operational intent, is ass backwards.

The regen on mine is definitely before normal. From a speed point of view it is backwards but the speed is controllable in regen and usually/always I'm dumping the bucket as fast as possible.
I don't think I've ever tried to control the speed in the normal range. In OP's case, he'd have to go through the fast range to get to the normal range, dumping the bucket on the way, so I don't think it would help him.
Mine definitely has more strength in normal. I can't roll the bucket enough in regen to lift the tractor's front end. Have to be able to lift the front end on a machine with a backhoe (and the rear) in order to sell it on-line

By its very nature regen produces less cylinder force. Its sumple physics.

My point exactly on order. IMO its ass backwards to have to go through fast dump to get to slow dump. Regen should be the 4th position just like float.The regen on mine is definitely before normal.
